// Strategic Significance
LaSalle County Nuclear Station on the Illinois River operates two reactors southwest of Chicago. The Illinois River at this location is a critical commercial waterway for agricultural commodity transport. The plant's 50-mile ingestion zone reaches into the Chicago southwestern suburbs including Joliet and Aurora making it one of the nuclear plants with the largest urban population in its ingestion zone.
// Civilian Impact Assessment
Chicago's southwestern suburbs including Joliet Aurora and Naperville fall within or near the 50-mile ingestion zone. The Illinois River below the plant flows toward its confluence with the Mississippi River. A significant release could affect river water quality for communities downstream through the Illinois and Mississippi river systems.
// Evacuation & Shelter Guidance
10-mile EPZ: Evacuate via IL-71 or US-6. Monitor IEMA broadcasts. 50-mile zone: Joliet Aurora and southwest Chicago suburbs monitor IEMA guidance. Avoid Illinois River fish during any release. Illinois River recreational activities would be immediately restricted.
